The little round pictures that you see in the margins throughout this book are icons that alert you to several different kinds of information.
The Tip icon lets you know what you can do to improve your understanding of an anatomical structure.
The Remember icon serves to jog your memory. Sometimes, the text is information that we think you should permanently store in your anatomy and physiology file. Other times, the info here makes a connection between what you’re reading and related information elsewhere in the book.
The Technical Stuff icon flags extra information that takes your understanding of anatomy or physiology to a slightly deeper level, but the text isn’t essential for understanding the organ system under discussion.
